Abstract
Performed on rats was study of the cause of appearance of stress reaction at action of hyperbaria upon organism. It was established that at the 5-h long action of gas mixtures (oxygen—nitrogen and oxygen—argon) under pressure of 0.35 and 0.5 MPa and partial pressure of oxygen of 0.02–0.03 MPa in camera 300 l in volume there was clearly realized stress confirmed by the corresponding markers. The appearance of stress was connected with density of gas mixture, which amounted to 6 g/l, that mechanically makes breathing difficult. On the other hand, use for respiration mixtures of elegas (SF6) with density of 6 g/l at normal pressure produces pronounced stress. At equal density, no difference was revealed in action of nitrogen, argon or elegas. Thus, use of high pressures requires light gases (helium, hydrogen, neon) that have low density.
